Abstract

Disclosed are cosmetic compositions comprising latex film formers chosen from at least one random styrene acrylate copolymer or derivatives thereof, and at least one acrylate copolymer or derivatives thereof, in combination with at least one coalescent and/or plasticizer. Also disclosed are cosmetic compositions comprising at least one latex film forming blend comprising (1) at least one random styrene acrylate copolymer and at least one acrylate copolymer or derivative thereof, or (2) at least two random styrene acrylate copolymers. Polyurethane latex dispersions may be incorporated into the compositions. Optionally, the cosmetic compositions may additionally comprise at least one coalescent and/or plasticizer in combination with the at least one latex film forming blend.

First claim

What is claimed is:

1. A cosmetic composition comprising at least one latex film forming blend comprising:
a. at least one random styrene acrylate copolymer having a Tg ranging from about 0° C. to about 50° C.; and
b. at least one acrylate copolymer or derivative thereof having a Tg ranging from about 30° C. to about 70° C.

2. The cosmetic composition of claim 1 , wherein the at least one random styrene acrylate copolymer is chosen from styrene/acrylates/ammonium methacrylate copolymers and styrene acrylic copolymers.

3. The cosmetic composition of claim 1 , wherein the at least one acrylate copolymer or derivative thereof is chosen from ammonium acrylates copolymers, acrylates copolymers, acrylic copolymers, and derivatives thereof.

4. The cosmetic composition of claim 1 , wherein the latex film forming blend is present in the cosmetic composition in a combined amount ranging from about 20% to about 80%.

5. The cosmetic composition of claim 1 , further comprising a coalescent and/or plasticizer.

6. The cosmetic composition of claim 5 , wherein the at least one coalescent is chosen from propylene glycol n-butyl ether and dipropylene glycol benzoate, and/or the at least one plasticizer is chosen from tributyl citrate, texanol ester alcohol, and diisobutyl adipate.

7. The cosmetic composition of claim 1 , chosen from nail compositions, make-up compositions, mascara compositions, hair-care compositions, and sunscreen compositions.

8. The cosmetic composition of claim 1 , further comprising at least one polyurethane latex dispersion.

9. A method of improving at least one property chosen from adhesion, water-resistance, oil-resistance, shine, and long-wear properties in a cosmetic composition, said method comprising including in the cosmetic composition a latex film forming blend chosen from latex film forming blends comprising:
(1) at least one random styrene acrylate copolymer having a Tg ranging from about 0° C. to about 50° C. and at least one acrylate copolymer or derivative thereof having a Tg ranging from about 30° C. to about 70° C.

10. The method of claim 9 , said method further comprising adding at least one coalescent and/or plasticizer to said cosmetic composition.

11. The method of claim 10 , wherein the at least one coaslescent is chosen from propylene glycol n-butyl ether and dipropylene glycol benzoate, and/or the at least one plasticizer is chosen from tributyl citrate, texanol ester alcohol, and diisobutyl adipate.

12. The method of claim 9 , wherein the cosmetic composition is chosen from nail compositions, make-up compositions, hair-care compositions, and sunscreen compositions.

13. The method of claim 9 , further comprising including at least one polyurethane latex dispersion in the cosmetic composition.
